{"id":"CVE-2026-114136","published":"2026-10-21T20:17:25.557","lastModified":"2026-10-22T17:21:57.293","description":"Django REST framework is a toolkit for building Web APIs. From 3.6.4 until 3.18.2, JSONParser.parse in rest_framework/parsers.py uses the client-supplied Content-Type charset value with codecs.getreader, which accepts byte-transform codecs such as bz2_codec rather than only text encodings. A remote unauthenticated client can therefore cause a compressed JSON request body to be expanded after Django has enforced DATA_UPLOAD_MAX_MEMORY_SIZE against only the wire bytes, allowing a very small request to consume substantial per-worker memory. The default parser set is sufficient, and any reachable endpoint that accepts a JSON body is affected. This issue is fixed in version 3.18.2.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-409","CWE-770"],"vendors":[],"products":[],"references":[{"url":"https://github.com/encode/django-rest-framework/commit/3c2634599b26a9f789b03045118dbc276117611a","tags":[]},{"url":"https://github.com/encode/django-rest-framework/releases/tag/3.18.2","tags":[]},{"url":"https://github.com/encode/django-rest-framework/security/advisories/GHSA-3547-9m27-7rxg","tags":[]}],"exploitRefs":[{"url":"https://github.com/encode/django-rest-framework/commit/3c2634599b26a9f789b03045118dbc276117611a","tags":[]},{"url":"https://github.com/encode/django-rest-framework/releases/tag/3.18.2","tags":[]},{"url":"https://github.com/encode/django-rest-framework/security/advisories/GHSA-3547-9m27-7rxg","tags":[]}],"hasPoc":true,"ai":null}
